HAND PRINTING-PRESS.

Specification of Letters Patent No. 24,655, dated July 5, 1859.

To aZZ whom it may concern.'

Be it known that we, A. NEWBURY and B. NEwUnY, both of Windham Center,in the county of Greene and State of New York,

have invent-ed a new and Improved Printing-Press; and we do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in which-- Figure l, is a longitudinal vertical andcentral section of our invention. F ig. 2, a plan or top View of thesame.

Similar letters of reference indicate corresponding parts in the twofigures.

To enable those skilled in the art to fully understand and construct ourinvention we will proceed to describe it.

A, represents a. frame which is properly secured to a platform or baseB, and a, a, are two parallel bars placed on the upper part of saidframe, one at each side. On the upper part of the frame A, the form bedC,

is placed, the bars a, a, in connection-with traverse pieces Z2, ZJ,forming sides to the bed.

D, represents the type or form placed on the bed C, and locked withinthe sides or bars a, a, and traverse pieces Z), b.

E. represents a frame, which is formed of two parallel bars c, c, thelower or inner parts of which are bent about at right angles to theupper or outer parts. rllhe outer paris of the bars c, c, are connectedby a bow or curved bar (Z, which has a handle e, attached. The bars c,at their loweror inner ends are fitted loosely on the shaft e, which isbelow the form bed C.

F, is a platen one end of which is provided with arms f, f, one at eachside. These arms are fitted loosely on a transverse shaft y, on theframe A. The platen F, is of rectangular form and corresponds in sizewith the form bed (l. To the upper surface of the platen F, a` bar G, isattached. This bar is fitted in guides ZL, attached to the back of theplaten and may be adjusted by set screws a', according` to the pressurerequired. On each end of the bar G, a friction roller ji is placed, andthese friction rollers are fitted in longitudinal slots Zr, in the barso, o, of the frame E.

H, is a frisket, one end of which is provided with arms Z, Z, which arefitted loosely on the shaft g, precisely similar to the arms f, f, ofthe platen F. This frisket is a rectangular frame which is made to fitaround the platen. To the arms Z, Z, of the frisket, the upper ends o-fspiral springs m, m, are attached. The lower ends of said springs beingattached to the platform or base B.

To one of the bars c, of the frame E, a rod is attached, said rod beingalso attached to a frame I, which is placed on a rock shaft J, on theplatform or base B. To the upper end of the frame I, two rods o, 0, areattached, at one end and these rods are attached at t-he opposite end toa roller frame K, which rests on the bars a, a, said frame beingprovided with proper ink rollers.

L, is a circular table, the upper surface of which is on a level withthe face of the form D. This table has its arbor fitted loosely within asocket or support M, and to the under side of the table and concentricwith it, a ratchet g, is attached. On the arbor of the table L, an armN, is placed loosely, and to this arm a pawl 1", is attached and kept ingear with the ratchet 1, by a. spring s. To the outer end of the arm N,one end of a rod O, is connected, the opposite end of said rod beingtted in the upper end of a bar t, at.- tached to the rock shaft J, therod having pins a, passing through it one at each side of the bar t.

l?, is a spring the lower end of which is attached to the platform orbase B, the upper end being made to bear against the table L.

Then the press is used for printing cards, the frisket H, is permanentlyattached to the platen by hooks c, la, and twoguide bars a, a, areattached to the frisket and eX- tend over the inner surface of theplaten. Between the arms Z, Z, of the frisket H, a shaft Q, is fitted,and on this shaft two sockets b', are placed. In each socket b, a bentplate or strip c, is placed, the ends of said plates or strips are bentupward to form stops. The bars a', a', may be adjusted nearer togetheror farther apart according to the length of the cards to be printed.

On the shaft g', an arm (Z, is secured by a set screw e', and to theshaft Q, an arm f, is attached at right angles, said arm having a spiralspring g, connected with it, which spring has a tendency to keep thestops c', against the face of the platen.

The operation is as follows :*The table L, is supplied with a requisitequant-ity of ink. The form D, locked on the bed C. If the frame E, is inan elevated position as shown in red Fig. 1, the platen F, will beraised, and the ink rollers in the frame K, will be at the inner side ofthe form D, having passed over the form as the frame E, was elevated. Asthe frame is depressed by the operator, ablank card is inserted betweenthe guide bars a, a', and the platen F, is forced down by the downwardmovement of the frame in consequence of the rollers j, y',

tting in the slots lo, 76, of the bars 0, 0, of the frame. As the platenF, descends the roller frame K, is moved outward over the form D, andtable L, by the rod a, frame I, and rods 0, 0, the form being properlyinked by the passage of the roller over it. rlie card is pressed downupon the form D, and receives its impression by pressingY down the frameE. As the frame E, is raised, the roller frame K, is moved inward overthe table L, and form D, and as soon as the roller frame leaves thetable and passes on the form D, the table L, will be rotated a certaindistance by the pawl r, acting against the ratchet g, the pawl r, beingactuated at the proper time by the rodO, and bar t. This intermittentrotation of the table L, causes the ink to be distributed evenly on therollers in the frame K. 'J ust previous to the platen F, reaching theend of its upward movement, the arm f', on the shaft Q, strikes the armd', on the shaft g, and the plates or stoops will be thrown out from theface of the platen and the printed card thereby allowed to fall out byits own gravity, between the lower ends of the guide bars a, a.

r The frame E, is then again depressed, an-

other blank card inserted between the guide bars'a, the plates or stripsc, being thrown against the face of the platen by the spring g, to stopthe card, as the arm F, leaves the arm d.

In case bills or ordinary sheets are to be printed, the bars a, a, andthe plates or strips 0', c, are removed. The hooks fu, fv, are alsoremoved so that the frisket H, will not be attached to the platen F,-thearm cZ, is adjusted toabout the center of its shaft g. The operation ofprinting the paper sheets is precisely the same as that of printing thecards, with the exception that the frisket H, is moved instead of theplates or strips c. The frisket being opened or thrown out from theplaten as the latter reaches the termination of its upward movement inconsequence of the arm cZ, bearing against the shaft Q. The blank sheetto be printed is consequently placed between the frisket and platen atthe commencement of the downward movement of the same, the printed sheetbeing previously removed. As the platen F, descends the springsvm, m,cause the frisket to move inward around the platen and grasp the sheet.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is:

- The arrangement and combination of the slotted frame E, adjustable barGr, platen F, roller frame K and rot-ating ink table L, substantially asand for the purposes herein shown and described.
